When people plan recreational outings, maps of United States recreation areas usually play a role, even if it's minor. Few realize, however, that there is an entire species of maps, even historical ones, devoted to recreation. These documents can unlock some of the most enjoyable experiences America has to offer.

Modern treasure hunters, otherwise known as metal detectors, use maps frequently during odysseys spent uncovering historical artifacts. Ghost towns, old home sites, stagecoach stops, and countless other treasure-laden opportunities can often only be found on historical maps. "I've hunted dozens of plantations and other historic locations," says Jess Allen, treasurer of Rusk County Treasure Hunters in Rusk County, Texas, "but, I would never have found them without my maps."

Other sports that regularly require maps are biking and hiking. Adventurous hearts can sniff out their next thrill in uncharted wilderness, but some of the most reliably mapped opportunities exist within the United States' National Parks. America's system is the outdoor lover's paradise, but it takes much research and preparation to thoroughly and safely enjoy all they have to offer. The mapping of these parks began with Yellowstone National Park in 1872, and today, maps of campsites, trails, bodies of water, and other attractions are routinely updated by the National Park Service.

Last but not least, try to find a sweet fishing hole with no map of the body of water you're on. The proper water map will show structure, depth, creek beds, marina locations, and just about everything else the fisherman needs for a successful day.

Incorporating maps of United States into your recreation planning will not only save you time and frustration, it nearly guarantees an enhanced overall experience.
